Overview
Anti-theft gate valve is a valve specially designed to prevent unauthorized use, mainly used in heating systems, oil fields and other places that need to prevent misappropriation of resources.

Working principle and application scenario

The working principle of the anti-theft gate valve usually includes a concealed clutch device, which requires a specific tool or key to operate. This design not only ensures the convenience of operation, but also greatly enhances the anti-theft effect. They are widely used in water supply, heating, petroleum, chemical and other fields, especially in the need to prevent the misappropriation of resources.
